Cesc Fabregas was always convinced of success with Chelsea when in talks over the summer.
The former Barcelona midfielder admits he assessed the Blues squad before putting pen to paper.
"When Chelsea came, of course I studied in my mind how I could fit in, but I also wrote down the team. I always write the team down," Fabregas told The Telegraph.
"I had spoken to the manager and I knew what he wanted from me, but after that I always try to analyse what kind of squad there is, if it's good for my type of football because sometimes you can be as good as you want but you don't fit in some certain styles.
"I felt it was a really good move for me after I wrote down the squad."
